"Acting on a word-of-mouth recommendation, we found exactly what we were looking for at Hanayuki Japanese Restaurant. Here we experienced fast and hugely amicable service, along with a calm, civilised atmosphere, enhanced by a rarely found lack of Muzak (an overwhelmingly tedious element of many restaurants), and lively conversation among the Japanese expat patrons whose presence began to prove the restaurant’s proficiency in providing authentic Japanese fare. Strolling down the charming foodie Mai Hac De Street, we knew we’d struck Japanese cuisine when we came to a restaurant where red paper lanterns inscribed with simple characters hung down to either side of sliding screen-doors. We were welcomed by a doorman, and a waitress showed us to one of the tables lining either side of the ground floor (there are three floors in total). The setting was fairly elegant but not over the top; chairs were comfortable, the settings, simple," writes Justine Reilly in The Vietnam News.
Maan… sometimes I hate linking out to this lame writing in the Vietnam News. However, there is method in the madness. FWIW, my favourite Japanese place in Hanoi is KY-Y.
